The ZX310S-4T2XT is a managed device with 2x2.5GBit and 2x10GBit Ethernet.
It is sold, among others, by Horaco as an unbranded device.
CPU: RTL8372
Flash: 2MByte Winbond W25Q16DV (U3)
PHY 2x RTL8261BE
While testing #246, I noticd that SFP did not light-up while forcing
2.5gbit link. This is because RJ45 and SFP share the same LED-settings.
But RJ45 has two leds-settings.
Solution is to add settings for SFP for both managed and unmanaged
variant.
I recently brought a "Ztyuav Z-QWYT0402", the insides looked identical to the
existing supported "Hisource Hi-K0402WS". Both of them have the
"PCB-K0402-V3.0" silkscreen.
I flashed the vanilla image and it seems to work great.
I changed the documentation to be more inclusive of other devices (including
adding a picture of mine). I suspect more devices might fall into this
"PCB-K0402-V3.0" bucket, for example the "YuanLey YS25-0402" with
the vlan switch also looks suspiciously identical from the outside.
I also added some details I noticed while flashing mine:
teardown, flash padding, how the selector switch actually works.
- machine.c/h: add MACHINE_FNS1200P with verified GPIO assignments for
both SFP ports, LED SET0 (amber 2.5G / green 1G-100M-10M) and SET1
(SFP all-speeds), led_mux from original firmware register dump, and
machine_custom_init() enabling LED_GLB_IO_EN bit 6
- doc/devices/FNS-1200P.md: device overview, port layout, serial
console (S1 three through-holes = UART0 115200 8N1 3.3V),
LED and SFP GPIO tables
- doc/devices/photos/FNS-1200P/: chassis front panel and PCB top photos
- doc/supported_devices.md: add FNS-1200P to the list
GPIO assignments and LED register values were cross-checked between
live GPIO observation (RTLPlayground gpio command) and an original
firmware register dump.
Add support for the ZX310S-4T2XH switch, which is a 4x2.5GBit + 1x10GBit + SFP
device. The device does not have any branding and is sold under different
brand names, in particular by Horaco. There is no branding on either label
nor PCB.
CPU: RTL8372
Flash: 2MByte Winbond W25Q16DV
10GBit PHY: RTL8261BE
UART header present, but solder holes are filled with solder that needs
removal, first, e.g with a 1.2mm drill.
The original firmware uses 57600baud 8N1
This splits the current MACHINE_KP_9000_9XHML_X definition into "V2_2"
and "V3_1" versions for the two known versions of this hardware.
Confirmed to work:
- LED configuration matches stock firmware
- Port ordering matches label
- A SFP can be detected and EEPROM read (I don't have a fiber cable to test link)
- Reset button presses are detected
It seems very likely that other versions are not compatible, so make it
clear by including it in the machine type and name. Also update the
documentation.
This board appears for example in the Davuaz Da-K6501W switch, and is
designed similarly to Hi-K0402WS.
However, it only has one SFP port and another 2.5G copper port using
RTL8221B 2.5G PHY instead. Also, some components on the board, like
additional LEDs, mode switch, and second flash chip are not populated.
Like earlier revisions of the K0402W(S) board, there is no UART, so
debugging is limited.
As this is an unmanaged switch, installation needs a flash programmer.
Looks like the SFP numbers are reversed, since GPIOs were mapped
to SFP numbers, the need to be reversed too. This fixes swapped
display of SFP stats on the webpage.
Added support for all leds on the device.
Stock port sets are slightly differently configured, where additional
LED0 on SET_0 and LED1&LED2 where configured for link/collisions/duplex.
This has not been reproduced as those lines are probably not connected
anywhere.
The SWTG018AS-A V2.0 is an 8x2.5GBit/s port + 1 SFP+ port unmanged device
It is sold in an unbranded casing e.g. by Ampcom.
Hardware:
SoC: RTL8373N
Additional PHY: RTL8224
Flash: Puya P25D40SH (4MBit, slimmer, not standard SOP-8 package!)
LEDs: 1 Green + 1 Orange per Ethernet port (green designates 2.5GBit)
1 Green LED for the SFP+ port
The photos already show a modified PCB: Unpopulated resistors R52 and R53
have been bridged in order to enable the serial console. The smaller flash
memory chip at U2 has been replaced with a Windbond 128MBit standard-sized
SOIC-8 chip in order to easily use SOIC clamps to flash the device. Also
the serial header has been populated.
The current code for entering commands via the serial CLI is completely
refactored and moved out of rtlplayground.c into a separate file cmd_edit.c
putting code into BANK2.
The serial ring buffer sbuf[] is now exclusively used for receiving
keys, including escape sequences (DEL will generate a 4-byte escape
sequence). The command is now held in cmd_buffer. This reduces
XMEM use, because the serial buffer can be much smaller.
Supported is only editing the current command line via backspace, del,
cursor left and right.
Because the code cannot distinguish escape sequences which are not yet
complete (because the serial isr has not yet put all characters into
the serial buffer) from the dozens of unsupported ones (F-keys/home,
Page up/down, cursor up/down...) they are ignored and remain in the
serial buffer until the ring-pointer overwrites them. This is standard
behaviour for consoles, which will print out garbage for unsupported
characters. In this implementation, the command line buffer and the
visible command line in the terminal are always synced, so garbage
can be removed again by ediing the line.
The code makes several redundant checks in order to prevent race-conditions
between the serial ISR and the comand-editing code.
The left and right SFP ports were swapped in the machine structure. They
are now correctly identified a comment is added. The custo LED-mux
is removed again, as this was accidentally added for demonstration
purposes. It is not necessary, as the device uses the default.
